Battery getting hot

[Stephen]

Hi
I have a 2007 Sportsmobile I bought four months ago , I have only been out in it twice so far
( planning to go out this weekend ) ,its stored in my workshops plugged into a power supply , I just went to move it & when I opened the door I could smell the battery was cooking , I unplugged the power cable & crawled underneath & felt both batteries , the rear one ( smaller )
was very warm , I think I am supposed to turn something off when plugged in & stored ?
I will replace the battery ,but I cannot find where Ive gone wrong ,in my manual . I would be grateful for any help .

You need to tell us a little more about your van.

Diesel or Gas w/aux battery

or Gas with one starting battery and one house battery?

Inverter or only the SMB supplied battery charger?

In general, a hot battery implies overcharging, but why?

Hi Mike

Diesel power , engine battery + large auxiliary , Tripp-lite battery maintanance charger , Ive removed the engine battery & put my digital tester on @ 750 cca ,it passed + volt meter almost 13 volts + load tested for ten seconds , passed that as well , I will put in a new battery anyway & clean the furry & corroded terminals .

Now I'm confused.

A 2007 Ford diesel should have two equal sized batteries under the side of the van. They are wired in parallel and should be replaced with the same size and type of battery at the same time.

And you have a large aux (house) battery.

Which one is getting hot?

Hi Mike

Sorry you are confused , the first posting I put up , I stated it was the rear battery , the second posting I stated it was the engine battery , Ive installed a new battery & cleaned & greased the terminals , I will plug the power cable in when I return from my trip & monitor the battery temp .

Thanks for all your help & guidance

You most likely had a bad Ford battery that prevented the charger from going into a "float" mode, which caused the excessive heat and odor. As mentioned, you will want to replace both of the Ford batteries that are located under the van on the passenger side. They should be covered by your Ford warranty if it is still valid.
